The erosion of Fourth Amendment rights, illustrated in real life:
A middle school in Pennsylvania was placed in "lockdown" at 2PM on Tuesday:Students were kept in their classrooms while three dogs searched the building, looking for marijuana, cocaine, crack, amphetamines, heroin and ecstasy.
The dogs were claimed to have "alerted" on 31 lockers -- this school might be the very fulcrum of the global trade in illegal drugs. So the authorities padlocked the highly suspicious lockers (along with neighboring ones), then went about securing a search warrant.
[...]
Oh yeah, no drugs were found. Zero-for-thirty-one. Better days ahead, drug sniffing pooches.
Of course these dog 'alerts' are cause to search your home, your person, or your car, because if we're going to win this war on drug there's no room for antiquated ideas like those in the Constitution.
